Most people can see the faint bluish line of their radial artery; place your fingertips here. Count the beats for 1 minute. Or, if you have a short attention span, count for 30 seconds and multiply by 2. During your workout, take your pulse about every 15 minutes and be sure to concentrate. You may want to slow down or even stop while you take your pulse.
Your pulse is a measure of how many times per minute your heart beats. You can find your pulse by lightly pressing on your skin anywhere there's a large artery, such as the side of your neck or the inside of your wrist just below your thumb. When you're resting your heart probably beats about 60 to 100 times per minute. When you exercise, your heart beats much faster, because it has to pump blood faster to supply your body's cells with the oxygen and nutrients they need to function during exercise. If you use an average of 80 beats per minute, your heart beats about 4,800 times per hour. That's a whopping 115,200 times per day. Over the course of a year, your heart would beat about 42,048,000 times! If you live to be 80 years old, your heart would have beaten approximately 3,363,840,000 times! That's over 3 billion heartbeats!
